BFM136 Branch-Feeder-MonitorTM
BFM 136
SATEC’s Branch-Feeder-MonitorTM (BFM) is our new generation energy management meter designed for energy and demand monitoring, load profiling, and multi-tariff (TOU), multi-client billing applications. Each BFM monitors up to 12 three-phase circuits, 18 two-phase circuits, 36 single-phase circuits, or any combination thereof. This flexibility makes the BFM especially suitable for multi-tenant facilities such as residential and office buildings, shopping malls, hotels, hospitals, universities, supermarkets and data centers. Ideal for both new and retrofit projects, the BFM’s compact size is designed to easily fit into existing panel boards, thus eliminating expensive retrofitting costs or allocating extra space for the instrument. The BFM provides the ideal solution for sub-metering applications and is designed to answer the monitoring and billing needs of multi-tenant facilities. The BFM monitors up to 36 current inputs via external sensors. Each sensor measures and reports the current and power consumed by each of the branch circuits at the panel board. For billing purposes, one can define single or multiple circuits for each customer. This flexibility allows one to simply reassign circuit groups to changing customers without complicated wiring changes. Further, the building owner saves time and effort by monitoring up to 36 circuits directly at the main panel board or load center. The BFM’s programmable alarm system enables one to take preventive maintenance steps to avoid unnecessary outages. SATEC also provides
split-core current transformers and wireless communication options to simplify installation.

The BFM provides a variety of electrical data such as per phase voltage and current, kW total, kVAR total, kVA total, PF total, Freq, kWH, kVARH, kVAH, demands and maximum demands. It also captures billing usage data in two formats, fixed rate or TOU based. The data can be viewed on the BFM’s LCD display (BFM136) or transferred via communication to software applications for more sophisticated analysis. The BFM allows easy integration with Energy Management or SCADA systems via the industry standard Modbus RTU/ASCII protocols. Through communications, one can access all measured parameters remotely and perform device configuration. Billing Tariffs vary according to the type of consumers - residential, commercial or industrial, and the amount of electricity consumed. The BFM’s TOU feature provides data in compliance with the rates set by the local electricity supplier and in accordance with the specified voltage level – high, medium, or low. The BFM provides information on peak demands and allows for the assessment of penalty if the power factor falls below a level defined by the local authority. PAS Software, eXpertPowerTM e-Service,and eXpertManagerTM system The BFM is bundled with PAS, our easy to use software designed for configuring, viewing and analyzing data from our instruments. For more advanced options, eXpertPowerTM, SATEC’s web-based energy management e-service, andeXpertManager provides real-time visibility and reporting capability for the entire power systemsover the Internet. PAS Features Included with every BFM Easy to use remote configuration software Supports off-line programming to allow easy
downloading of a standard configuration to multiple instruments
Supports scheduled polling, viewing of real-time data, and the automatic retrieval of load profile.
Bill Comparison via eXpertPowerTM The BFM provides eXpertPowerTM all the necessary data to perform bill comparisons. Facilities with several utility meters can utilize eXpertPowerTM to combine meters for billing, resulting in significant cost savings. Data Management with eXpertManager The BFM136 integrates with SATEC'seXpertManager system to provide a real timedata acquisition and control system that allowsfacility operators to manage data.
The BFM can be configured to monitor 12 3-phase circuits, 18 2-phase circuits, 36 single-phase circuits or any combination thereof. The sub-meter configuration is performed through an intuitive interface with the PAS software. Virtual totalization sub-meters A minimum of 4 totalization sub-meters Allows for automatic totalization of multiple
sub-meters that belong to the same tenant BFM Measurement Parameters Once the sub-meters have been properly configured, each sub-meter provides the following measurement parameters: Real-time ♦ Voltage and Current per sub-meter ♦ Watts per phase and total sub-meter ♦ VARs per phase and total sub-meter ♦ VA per phase and total per sub-meter ♦ PF per phase and total per sub-meter ♦ Frequency
